Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical equipment technology, specifically to an energy-saving dome-shaped ring cooler. Background Technology
[0002] The ring cooler consists of a wind box, a trolley, and a discharge chute. The trolley has a trapezoidal planar structure with upper and lower layers. The upper layer has grate plates, and the lower layer is a base plate with sealing tape along the edge. Between the upper and lower layers is a support plate with ventilation holes. The cylindrical body, composed of irregularly shaped beams and inner and outer side panels, presses against the sealing tape along the edge of the base plate. The ring cooler is short for ring-type cooler. Its function is to effectively cool the hot sintered ore discharged from the sintering machine. Compared with belt coolers, ring coolers have advantages such as smaller footprint, lower investment, and higher equipment utilization.
[0003] In industries such as metallurgy and building materials, the ring cooler is a key piece of equipment for cooling high-temperature materials such as sintered ore and pellets. Its energy consumption and cooling efficiency directly affect the overall energy efficiency and product quality of the production line. However, the existing ring coolers usually adopt a flat-top steel structure. Due to the complicated design of the steel structure, it is difficult to support the formwork during construction. The fume hood casting process is complicated. The refractory material is prone to cracking due to thermal expansion and contraction. The hanging bricks are prone to breakage under long-term stress, which leads to refractory material falling off. Frequent repair and replacement of refractory material increases maintenance costs and production downtime. At the same time, the flat-top structure has insufficient heat storage capacity, making it difficult to stabilize the chain-loop thermal process. Utility Model Content
